About Dr Ong

Dr Ong Kong Wee runs his own practice at K W Ong Breast and General Surgery Clinic at Mount Elizabeth Novena Hospital and Farrer Park Hospital. Currently, he is also the Medical Director of Concord International Hospital.

His main clinical focus is on the diagnosis and management of benign and malignant breast conditions, based upon up-to-date medical evidence and techniques. His clinical interests include minimally invasive breast surgery, sentinel lymph node biopsy, breast-conserving surgery and breast reconstruction for breast cancer.

He was the Founding Head of the SingHealth Duke-NUS Breast Centre from 2014 to 2018, which is the largest centre in Singapore treating the full spectrum of breast conditions. In 2018, he received a 20-year Long Service Award in recognition of his years of contribution.

In 2012, he pioneered the technique of Intra-Operative Radiotherapy in the treatment of early breast cancers. Given his expertise in minimally invasive breast biopsies such as vacuum-assisted needle biopsy and hookwire localisation, he has been a Regional Medical Consultant to Becton Dickinson since 2018.

Dr Ong has a keen interest in breast cancer research and has many publications in top journals such as Nature Genetics, Lancet Oncology and Clinical Cancer Research.

Dr Ong is actively involved in medical education and training. He was Adjunct Assistant Professor at Yong Loo Lin School of Medicine, National University of Singapore, and Duke-NUS Graduate Medical School. He served as Director of Resident and Student Mentorship at the Academic Clinical Program (Surgery) in SingHealth and was a Clinical Physician Faculty for the SingHealth General Surgery Residency Program. He was awarded the Outstanding Faculty Award in 2014. He has also trained many breast surgeons from neighbouring countries, including Philippines, Indonesia and Myanmar. He is frequently invited to lecture at local and international breast cancer conferences, and to conduct surgical workshops in the region.

Patient care is of paramount importance to Dr Ong. His efforts have been recognised at the National level, with a Special Mention in Customer Service (Healthcare) category at the Singapore Experience Awards in 2009 and a Silver Award at the Singapore Health Quality Service Awards.
